Effort-based estimation, three-point estimation, and analogous estimation are all commonly used techniques for estimating project tasks. Effort-based estimation involves estimating the effort required for each task and then converting that effort into a duration based on the available resources. Three-point estimation involves providing optimistic, pessimistic, and most likely estimates for each task and then calculating a weighted average. Analogous estimation involves using historical data from similar projects to estimate the duration of tasks in the current project. Risk-based estimation, however, is not a commonly used technique for estimating project tasks. While risk assessment is an important part of project planning, it is not typically used as a primary method for estimating task durations.
